what to do with web pictures after calibrating my monitor?

Discussion in 'Digital Cameras' started by Michael Greenberg, Aug 26, 2003.

  1. Hello everyone!

    I just bought colorvision Spyder Colorimeter to calibrate my monitor. The
    prints from digital files now are wonderful but the images I have created
    for the website before purchasing the system look horrible due to the change
    of colors. (my monitor was not calibrated before). I'm wondering if I should
    use calibrated monitor while building for the web or use old monitor profile
    for the images not indented for print.

    Thank you in advance.
    Michael

    Use your calibrated monitor to make your web graphics.

    But just remember... most people don't have calibrated monitors - but
    that's the nature of the game.

  3. If you want to be judged on your photographic ability, it's probably
    better to get your web images as close to 'perfect' as you can, so I would
    suggest changing them to look best with the new calibration.

    Not everyone will have their own monitors calibrated (actually, very
    few will, including me), but they will be used to the overall red tendency
    or whatever. If your images are different from what is generally a neutral
    color balance, it will be noticeable, regardless of whether they now look
    *better* on some people's monitors. And worse on just as many.

    I'm not familiar with too many editing programs other than Photoshop,
    but it's possible you can make a simple default set of 'actions' or
    corrections to quick-change your current web images. Open, F2, and Save,
    baboom. Photoshop will also let you do entire batches, such as a complete
    folder. Should be a relatively easy Curves or Color Balance adjustment.

    Good luck!

    It may help, especially to get consistent colour across images in an
    identical medium of presentation and under identical ambient lighting, BUT,
    no matter what you do a monitor is fundamentally capable of only 256
    variations each of R, G or B colours + brightness and contrast variations -
    that is the gamma limitation - and is limited to about 16.7 million
    variations. The human eye, however, is capable of millions more subtle
    perceptual variations. No amount of colour correction, adjustment or
    calibration YOU do will improve the visual appearance on a monitor, or for
    that matter a printer, that is not calibrated to the exact same state that
    yours is.

    Colorimetric calibration is used in networks connected to, and associated
    with, printing for just that reason of "consistency" but, even there, does
    not guarantee that the repro image will be exactly the same as the
    original - only that it will "appear" closely the same from machine to
    machine and provide a measure of tonality across changing media. Remember
    that, in viewing on screen, you are seeing an illuminated RGB image but in
    printing (especially commercial print work) the printer or press is printing
    in CMYK and the viewed image depends on reflected light which may vary in
    quality as to it's colour makeup.

    There is also dependence on even surface texture of the (output to paper)
    medium such as the difference between newsprint vs coated glossy offset
    paper; or between a photo printed on gloss or matt surfaced photographic
    paper; colour repro is even dependent, to some extent, on the brand of paper
    used and it's inherent "whiteness" or colour variations.

    To a human viewer as well, we don't all see with the same gamma range...and
    some particular colours may not be seen at all...it's called
    colour-blindness. Calibrating to your "eye" does not guarantee that a second
    person would not find the image out of gamma for them.
